PAUL HANSON, OF WILD HORSE, COLORADO.

BUTTER-MAKING MACHINERY.

To all 10. 1.01. it may concern Be it known that I PAUL Hanson, a citizen of the United States, residing at \Vild Horse, in the county of Cheyenne and State of Colorado, have invented a new and useful Improvement in Butter-Making Machinery, of which the following is a specification.

My invention relates to improvements in butter making machinery and its object is to provide a combined churn and butter worker having the most improved features for churning cream and handling the resulting butter, and at the same time so construct it that it may be inexpensive in manufacture and simple in manipulation.

The structure of the churn body together with its cover and cover lock and means for mounting it operably in its supporting frame and other details of construction constitute the subject matter of this invention.

In the drawings with which I have illustrated my invention and which form part of this specification, Figure 1 is an elevation, part in section showing the churn body mounted on its supporting frame; Fig. 2 is another elevation of the churn and support as shown in Fig. 1; Fig. 3 is a section on the line XX, Fig. 1 showing the interior of the churn receptacle; Figs. 4 and 5 are fragmentary sectional views on the line Y Y, Fig. 2; Fig. 6 is a view in perspective of the lifting shelf; Fig. 7 is a sectional view of the support for the shelves; Fig. 8 is a detail of the stop button, and Fig. 9 is an end view of the butter worker showing the end plate.

In the above drawings I have shown a churn body or receptacle A mounted rotatably on a supporting frame B and having within it a butter worker C. The butter worker C and body A being operable by a mechanism D including a pair of gears and an operating handle. A lifting shelf E is positioned within the receptacle A and a door F of special construction is provided giving access to the receptacle A.

The frame B consists of base parts 2 resting on the floor on which the machinery stands and a pair of uprights 8 connected with each base part ,2 and sloping together toward their upper extremity a cross piece 1 being placed between the uprights 3 and connected thereto by bolts 5 passing through the uprights and ends of the cross piece.

The upper ends of the pairs of uprights 3 Specification of Letters Patent.

Application filed December 22, 1911.

are embraced by a casting 6 having a rib 7 lying between the uprights receiving a transverse bolt 8 connecting the uprights thereto. The rib 7 spaces the uprights constituting each pair apart and coacting with the bolt 8 materially strengthens the frame in a simple and effective manner. Castings 6 contain bearings 9 for the stud shafts 10 and 10.

The churn body or receptacle A is a parallelepiped having ends-12, sides 14, a bottom 15 and a top 16, these terms being relative to the position of the churn body as illustrated in the drawings. The ends are inset each being formed with a tongue 13 on its edges fitting a groove 13 on the inside of the sides top and bottom of the churn to form a llquid tight joint. At the ends of the sides and bottom are provided slats 17 which rest on the walls of the churn opposite to the ends 12. Tie-bolts 18 pass through the slats 17 near their ends and are provided with nuts 19 at their extremities for the purpose of tightening the bolts upon the slats 17. These tie-bolts l8 assist in holding the walls of the churn together. By this means all of the walls of the churn may be readily pressed together to tighten seams in the material of which they are made.

In one of the sides 1e adjacent to the bottom 15 of the churn is provided an aperture closed by the plug 20 for drainage of the churn receptacle. A. screen 21 of meshed fabric covers the aperture on its inner side to prevent the passage of particles of butter fat out of the churn during the process of drainage. \Vashers 22 are provided beneath the nuts 19 on the slats 17 to protect the wood work of the slats.

The top 16 of the churn is provided with reinforcing pieces 23 which extend the full length of the churn and receive the head ends of two pairs of bolts 18 besides helping to support the locking'bars 27 of the door F. The door F consists of a body part 21 filling the space freely between the reinforcing pieces 23 and having cleats 25 adjacent to the ends 12 of the churn and extend through the aperture in the top 16, being beveled at one side and at their ends to fit conveniently into the aperture. The cleats are fastened to the body 24 in any convenient manner, preferably by means of screws extending through the body into the cleats.

Between the body 24 at its edges and the top 16 of the churn is inserted strips of cork 26 extending entirely around the aperture or hatchway in the top and adapted when the cover is fastened on, to close the aperture tightly against the passage of liquid during the operation of the churn.

The"door F' is fastened in place on the churn by means of locking bars 27. One extremity of each bar 27 is socketed in a light casting 28 attached to the reinforcing pieces 28 by screws 29 and the bolts 18. The opposite ends of the bars 27 are adapted to be engaged by a fastener 30 mounted on the opposite piece 23 and provided with a bev eled rotatable catch 30 which is adapted to engage the ends of the bars 27 and force them tightly down upon the door F of the churn. The fastening parts 28 and are simple in construction and readily replaced when worn while the bars 27 may be made of wood or metal.

lVithin the receptacle A a lifting shelf E is provided extending from the side wall of the churn substantially to its axis and adapted to intercept the entire contents of the churn at each revolution. The lifting shelf E is formed with end pieces 31 to which are attached slats 32 extending the full length of the churn. The slats have beveled sides 33 directed downward in the normal position of the churn. The lifting shelf E is supported on cleats 34E fastened to the ends 12 of the churn by means of screws 35 or in any suitable manner. Lugs 36 on the upper surface of the cleats 3st fit into the openings between the slats 32 engaging the beveled faces of the slats to hold the lifting shelf E in position longitudinally of the cleats 34. The corners of the cleats may be beveled to give a neat appearance to the churn and to assist in cleansing the interior. In each end 12 of the churn is provided a stop pin 37 which impinges on the extremities of the end pieces 31 and cooperate with the cleats to prevent movement of the lifting shelf E toward the axis of the churn.

A locking button 38 is mounted rotatably on the wall 14 of the churn by means of a screw 39 or in any suitable manner so that its extremities e0, in the normal position of the button, impinge on the extremities of the end piece 31 opposite to the pins 37, in this way locking the lifting shelf E down against the slats 34: and pins 37. The button 38 may be rotated out of its normal position with its longest diameter extending longitudinally of the churn to permit the raising of the lifting shelf E off from the slats 84 and its removal from the churn through the hatchway.

Between the lower extremity of the lifting shelf E and the opposite wall 14 of the churn is mounted the butter worker C which is provided with vanes 41 and extends nearly the entire length of the churn receptacle being journaled on its ends to revolve within the receptacle.

At the operating end of the churn at which is located the operating mechanism D,

the butter worker C within the receptacle A, is provided on its end with a spider 42 attached thereto by suitable screws 43 and having on the axis of the worker G a square socket 4st adapted to the reception of a squared end 15 on a shaft 4-5 received therein to operate the butter worker. The shaft 45 is journaled in the end wall 12 of the churn in a casting 16 which carries the shaft 10 on which the churn is journaled and carries without the churn a pinion 47. A packing washer 47 of yielding material such as leather is inserted between the squared head 45 and the casting 46 on the shaft 45 for the purpose of making a fluid tight joint.

The opposite extremity of the butter worker C is provided with a block 48 (see Fig. 5) of hard wood socketed therein upon its axis and having a recess 4L9 in which. is received a pin 50 threaded in a casting 51 which is secured on one of the ends 12 of the churn. The pin extending through the casting is adapted to support one end of the butter worker and hold the squared end 45 in the recess 44. A cross pin 52 is fixed in the head of the pin 50 to assist in adjusting it, A wear pin 53 is fixed in the end of the butter worker on its axis to resist end wear of the pin 50.

The castings 4,6 and 51 on which are fixed the shafts 10 and 10 journaling the churn, are formed with cross ribs 54 strengthening and lightening the castings. The castings are fastened to the ends 12 of the churn by means of screws 55 or in any other suitable manner in such a position that the shafts 10 are upon the axis of the churn. The shafts 10 and 10 extend longitudinally of the axis of the churn, outward from its ends, and are journaled in the castings 6 on the frame B as previously described. The shafts extend through the castings 6 and the shaft at the operating end of the churn is provided with a handle 56 fixed thereon by means of a set screw 57. A collar 58 is fixed. on the shaft 10 at the other end of the churn by means of a set screw 59. The operation of the handle 56 rotates the connected shaft 10 and the churn body A fixed relatively thereto.

At the operating end of the churn. a gear wheel 60 is freely journaled on the shaft 10 between the castings 4G and 6, the bearing of the wheel extending into the casting (i to impart stability in operation. The shaft 10 is rigidly secured to casting 46 by pin 516'. The gear wheel 60 is provided with an internal gear face 61 having teeth meshing with the pinion 47 to rotate the butter worker. Integral with the gear wheel 60 is a socket piece {32 in which is fixed a handle 63 by means of a bolt 64. The gear is formed of metal while the handle 63 may be made of wood for ease in replacement.

A stop 7 5 in the form of a button is pivotally mounted by a bolt 76 upon one of the pairs 3 of uprights of the frame and is movable into and out of engagement be tween pairs of shoulders which are formed by notches 77 in the end edges of the sides of the churn. The engagement by the stop with one notch is such as tohold the churn with its opening uppermost while the other engagement is such as to hold the churn at an angle with its opening at one side. A lug 78 integral with the gear casting 60 is provided so that when the stop 7 5 is moved out of engagement with the churn A and into the medial position illustrated by broken lines '75 in Fig. 1 it engages said lug 78 and prevents the revolution of the gear 60. Thus the operation of handle 56 while the lug 78 is engaged causes the butter worker to operate at high speed,

It is evident that the rotation of the churn receptacle A may be secured by means of the operating handle 56 and that the handle 63 and gear 60 normally rotate with the churn when the stop 7 5 is withdrawn from the position shown in Fig. 1 through friction of the parts. The rotation of the gear 60 with the churnproduces no relative movement between the gear 60 and the pinion l7 and the butter worker C does not rotate on its axis. This is the normal position during the churning operation before the working of the butter has begun. To start the operation of the butter worker G the stop 7 is moved into engagement with the lug 78 as illustrated in Fig. l by broken lines Thus holding gear 60 stationary and operating the pinion 4L7 while the churn revolves or the handle 68 can be engaged by hand holding the gear (30 stationary while the stop 75 is moved completely out of engagement with all operating parts. Upon the starting of the rotation of the churn under these conditions the churn revolves with relation to the gear 60 and the pinion 4.7 is rotated thereby thus operating the but ter worker C fixed thereto.

The position of the pinion 4L7 within the gear 60 causes the rotation of the butter worker C in a direction opposite to the churn body A and the vanes 41 of the butter worker C are fonied with their edges projecting in the direction of rotation of the butter worker in the normal operation of the churn. The lifting shelf E is so positioned that in the rotation of the churn the contents thereof are thrown by said shelf upon the butter worker C and against the vanes 41. The pinion 47 being smaller than the gear 60 causes the butter worker to rotate at a relatively high speed to the churn during its operation. being eccentric to the axis of the churn causes efiicient and effective results.

In accordance with the patent statutes I have described the principles of operation of my invention together with the apparatus which I now consider to represent the best embodiment thereof but I desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.
